This invention relates to air turbin The principal Object of this invention is to provide a device of a turbine type for the purpose of exerting lifting force so that the device will move upwardly into the atmosphere.

A further object is to provide a device having a' which will appear as the description proceeds, the

invention resides in the combination and arrangement. of parts and in the details of construction hereinafter described and claimed, it being. understood that changes in'the precise embodiment of the invention herein disclosed, can be made within the scope of what is claim d, without departing from the spirit of the inven on. The invention is illustrated in ing drawings, wherein:'

It is my contention that an air turbine will be I a marked development-in the utilization of various 5 aircrafts and will for many practical purposes supplant the use of the balloon and other aircrafts now in common use. It is'also believed that with my device aircrafts may ascend into the atmosphere in a vertical manner, thereby doing away with the necessity of large areas for airp'orts.

It is also mycontention that my device will make it possible to set up a lifting power overcoming the resistance of the atmosphere coming in contact with the upper-surface of thedevice when 'mov-t ing in air. In orderto do this I have utilized as a basis, natural laws of physics including gravity,

atmospheric pressure, and momentum.

In order to comprehend the structure and working of the device I take up the description of the construction and movement of parts involved.

By referring to Figures 1 and 2 it will be seen that the device consists of a dome shaped member I provided with an upper central opening 2. This dome shapedmember I is provided with a plurality of support members 3 secured at their lower 6 Claims. (01. -159) ends to a horizontal disk 4. This horizontal disk 4 supports a tubular member 5 provided with'a shaft 6. The lower end I of the shaft 6 has keyed thereon a beveled gear 8 which functions with a beveled pinion 9 which is keyed to-a power shaft III. This power shaft III may be energized by any suitable power of relatively lightweight such as is now used in motors for aircrafts. When the power-shaft III is revolved the shaft 6 is caused to rotate, setting in motion a pluralit'yof vanes II which are attached to arms I2. These arms I2 are secured to keyed fittings l3 and I4 positioned on the shaft 6. It will also be seen that the upper end I5 of the shaft 6 is supported by a boxing I6 and by a ball bearing support I1 at a point I8 on the shaft 6. It will also be seen that the boxing I6 is supported by means of radial bars I 9 which in turn are secured at their outer ends to the top of the dome shaped member I. By refer-. ring to the drawings it will be seen that there is a central horizontal circular plate 20 centrally attached to a flange 2| formed on the upper end of the tubular member 5.

By referring to Figure 3 it will be seen that this circular horizontalplate is secured to a. plurality of radial arms 22, the outer ends of which are s'ecured to the outer lower periphery-23 of the dome shaped member I by means of rivets 24.

By referring to Figures 1 and 3 it will be seen that vertically positioned near the outer edge of this central ho rizontal circular plate 20 there are a plurality of curved plates. 25 so arranged that their inner ends 26 are each spaced apart from a companion curved plate 25, thereby leaving a passageway through which .air is forced when the vanes II are rotated clockwise. It will also be seen that at a point 28 thereis a hinged closure member 21 which stands open when the vanes I I are forcing air through the passageway between the ends 26 and the point 28. When the vanes II are stationarythe air flow reverses through these openings thus closing the hinged closure ,member 21., when closed, the hinged closure member 21 in effect, converts the entire device into a parachute providing that the entire structure is of suflicientsize to act efliciently in this would have a tendency to carry the air around I with them but with a lilnited number of vanes the dome shaped member, a plurality of vanes rotatout being carried around with the vanes.

In the operation of the device it is believed that when the air is forced out through the air passages above described, the air is forced into an outer concentricv chamber 29 and finally flows 'out underneath the dome shaped member I. The

inlet consists of the, upper central opening 2. One of the important principles upon which the device operatesis the relative difference in the inlet of air and the outlet of air. It is believed that this. action is setup by reducing the space of outlet to nea'rlyone-half of the space of inlet and by using the difference as momentum back of the vanes' ii ,there will be a reduced downward pressure on the dome shaped member I and an upward lifting pressure under the dome 'shaped member I and outer concentric chamber 29, thereby exerting an upward movement of the device and parts attached to the same.

What I claim is: 1 .-In a device of the class described, a dome shaped member, a central opening in top of said ing centrally underneath said dome-shaped member, aplurality of curved plates surrounda ing said vanes, the inner ends of said plates -spacedapart from the companion plates in torder toleave a passageway for outlet of air, to gether with means for propelling said vanes.

2. In a device of the class described, a dome shaped member, a central opening in top of said dome shaped member, a plurality of vanes rotating centrally underneath 'sa'id dome-shaped member, a pluralityof curved plates surrounding said vanes, the inner ends of said plates spaced apart from the companion plates in order to leave a passagewayfor outlet of air, said opening in top of domeproviding a relatively larger inlet for air than said passageway provides for outlet of air, together with means for propelling'said vanes.

3-. In-a device of the class described, adome shaped member, a central opening in top of r' said dome shaped member, a plurality of vanes rotating centrally underneath said dome-shaped member, a plurality of curved plates surrounding said vanes, a horizontal circular disk supported underneath the plurality of curved plates and rotating vanes,

, air is exploded out throughthe air passages withspaced apart from the companion plates in orthe inner ends of said plates der to leave a passageway for outlet of air, said platesfsurrounding said vanes, a horizontal circular disk supported underneath the plurality of curved plates and rotating vanes, a passageway between the ends of curved plates for the outlet of air, a hinged closuremember in said passage- 'way to be opened and closed by the pressure of air as described. I

5. In a device of the class described, in combination adome shaped member, a central opening in top of dome shaped member, a plurality of vanes having a receding position rotating. centrally underneath said dome-shaped member, a

plurality of curved plates surrounding said vanes, a horizontal circular disk supported-underneath said curved plates and rotating vanes,

a passageway between the ends of curved. plates for the outlet of air, a hinged closure member to ends of curved plates to be opened and closed by the'pressure of air as described.

6. In a device of the class described, in combination a dome shaped member, a central opening in top of dome shaped member, a plurality of vanes havinga receding position rotatingf centrally underneath said dome shaped member, a plurality of curved plates radially spaced from said dome and surrounding said vanes, a horizontal circular disk supported underneath said curved plates and rotating vanes, a. passageway between the adjacent ends of said curved plates and secured in a relative radial position in order to provide for the outlet of air, a hinged closure member secured to ends of curved plates to be opened and closed by the pressure'of air as de-.

scribed.
